A kinetic Monte Carlo simulation of dislocation motion was carried out. The dislocations were assumed to be composed of pure edge and screw segments which were confined to a fixed lattice. The stress and temperature dependences of the dislocation velocity were studied, together with finite-size effects. It was proposed that surfaces and boundaries could play a significant role in the velocity of the dislocations. The simulated dislocations were shown to exhibit a kinetic roughening, in accord with exponents which were predicted by the Kardar-Parisi-Zhang equation.
